📚 Making Entries: Recording Data in IGCSE Chemistry Practicals | IGCSE化学实验数据记录：规范填写要点

In IGCSE Chemistry practical work, “making entries” refers to the process of recording measurements, observations and calculated values clearly and accurately in a results table. Examiners look for complete units, sensible precision and careful observations. This guide explains how to make entries that meet IGCSE standards.

在IGCSE化学实验中，”记录数据”指的是将测量值、观察结果和计算值清晰准确地填写到结果表格中。阅卷人关注单位是否完整、精度是否合理以及观察是否细致。本指南将解释如何做出符合IGCSE标准的实验记录。

1. What Does ‘Making Entries’ Mean in IGCSE Chemistry? | IGCSE化学中’记录数据’指什么？

In practical chemistry, an entry is any item of information you write down while carrying out an experiment. This includes numerical readings such as mass and temperature, as well as descriptive observations such as colour changes or gas bubbles.

在化学实验中，记录条目是指你在实验过程中写下的任何信息。这包括质量、温度等数值读数，也包括颜色变化或气泡等描述性观察。

In Cambridge IGCSE Chemistry, practical skills are tested through Paper 5 (Practical Test) or Paper 6 (Alternative to Practical). Both papers require you to make entries that are accurate, complete and easy to read.

在剑桥IGCSE化学中，实验技能通过 Paper 5（实验操作考试）或 Paper 6（实验替代考试）进行考查。两份试卷都要求你做出准确、完整且易于阅读的记录。

2. The Structure of a Results Table | 结果表格的结构

A good results table has a clear title, columns with headings that include units, and the independent variable in the first column. For example, if you change the volume of acid, the volume goes in the left column and the measured temperature goes in the right column.

一个良好的结果表格应有清晰的标题、包含单位的列表头，并将自变量放在第一列。例如，如果你改变酸的体积，则酸的体积放在左列，测得的温度放在右列。

Each column heading should show the quantity and unit separated by a slash, such as Volume of acid added / cm³ or Temperature / °C. The cells should contain only numbers, not units.

每个列表头应以斜线分隔物理量和单位，例如 Volume of acid added / cm³ 或 Temperature / °C。单元格中只填写数字，不填写单位。
